WNMG080408-RM5 WMP30G RM5 Wendeplatten - Walter Tools

Efficient machining of stainless steel is enabled by the combination of the Tiger‑tec Gold WMP30G grade and the RM5 chipbreaker, while the Trigon 80° geometry with a 0.8 mm corner radius provides consistent edge stability; order the WNMG080408-RM5 WMP30G turning insert directly via (Metav Werkzeuge) or ask our consultants if needed.

WNMG080408-RM5 WMP30G turning insert — Tiger‑tec Gold, for stainless steel — Walter Tools

WNMG080408-RM5 WMP30G is a Trigon 80° turning insert with a Tiger‑tec Gold coating, engineered for reliable, medium-to-robust stainless steel turning under demanding conditions

• Tiger‑tec Gold WMP30G coating for stainless steels
• RM5 chipbreaker for stable chip formation
• Trigon 80° geometry with 0.8 mm corner radius

Increased productivity for stainless steel turning

The WNMG080408-RM5 WMP30G insert combines a coated carbide substrate with the Tiger‑tec Gold technology to tackle the typical challenges of machining stainless steel: material toughness, tendency to build-up on the cutting edge and elevated thermal load. The WMP30G grade supports a controlled wear pattern that prolongs tool life and reduces unplanned interruptions. By favouring a stable cutting edge and predictable abrasion behaviour, machining cycles are more consistent and process control is simplified.

Stable chip control and surface quality

The RM5 chipbreaker is designed to form and evacuate chips reliably in turning operations of stainless steels. Controlled chip formation reduces the risk of entanglement and improves surface finish; the upshot is fewer secondary operations and less machine downtime. The insert’s negative rake (0°) and Trigon 80° geometry distribute cutting forces in a way that is advantageous for interrupted cuts and shoulder work, where robustness and edge retention are essential.

Geometry that supports repeatable results

With a 0.8 mm corner radius and compact plate proportions (size 08, thickness 04), the geometry of the insert balances edge strength and versatility. The Trigon 80° shape allows for secure seating in a broad range of toolholders while the moderate corner radius reduces the likelihood of chipping under increased feed or interrupted cuts. For users less familiar with insert geometry: a larger radius improves edge life but increases cutting forces, whereas the chosen 0.8 mm radius offers a practical compromise for general stainless‑steel turning.

Practical guidance for integration into production

The coated grade and chipbreaker are intended for medium to robust cutting conditions typical in industrial stainless‑steel applications. The Tiger‑tec Gold coating enhances thermal resistance and protects the cutting edge under elevated temperatures, enabling higher cutting speeds compared with uncoated grades in similar conditions. When adapting cutting data, prioritise stable clamping and sufficient coolant or controlled dry strategies, since the insert is optimised to maintain process stability and consistent component quality rather than maximum aggressiveness.

FAQ

What materials is this insert suitable for?
The WNMG080408-RM5 WMP30G insert is optimised for stainless steel (ISO group M) and is intended for medium to robust cutting conditions in that material group.

How does the RM5 chipbreaker affect machining?
The RM5 chipbreaker promotes reliable chip formation and evacuation during turning of stainless steels, which helps to maintain surface quality and reduce rework caused by poor chip control.

What advantages does the Tiger‑tec Gold coating provide?
Tiger‑tec Gold on the WMP30G grade increases thermal resistance and wear protection, supporting longer tool life and more consistent cutting performance under elevated temperatures typical for stainless‑steel machining.

Is the geometry suitable for interrupted cuts?
Yes, the Trigon 80° geometry combined with a negative rake and 0.8 mm corner radius provides robustness and reduced risk of edge chipping during interrupted or shoulder turning operations.

Can the insert be used with standard toolholders?
The Trigon 80° form and the WNMG clamping design are compatible with a wide range of standard turning toolholders that accept WNMG inserts.
